Find out which resembles the pattern formed when the sheet is folded along the dotted line:
Sheet
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) →
When the sheet is folded along the dotted line, the right half turns over onto the left half, so each of its lines reappears as its mirror image in the fold line. The three lines from the centre (blue) now run to the top-left corner, the middle of the left side and the bottom-left corner; the first of them falls on the left half’s own diagonal.
